A few days ago, the ZTE sensation hit the country and pushed the topic of domestic chips to the cusp of turbulence. The gestation, innovation and growth of the Chinese chip industry formed a series of question marks in the minds of the followers. Based on this, at the 2018 Guangya Exhibition site, Thousands of reporters were fortunate to have invited Dr. Liu Wei, general manager of Shenzhen Lihe Microelectronics Co., Ltd., a leading manufacturer of domestic communication chip designs, to share his extensive industry experience and views on the future development of domestic chips.
Under the wave of artificial intelligence, how can the wisdom of the Federation achieve landing?
In the age of artificial intelligence, everyone is pursuing intelligence. Everyone seems to have a dependency on intelligence. For example, from the initial smart phones to today's smart homes, smart communities, smart cities, etc., intelligence is everywhere. Intelligent control, that is, the manifestation of the device in the Internet under the influence of the device. How to achieve the connection between the devices and the user experience, is one of the criteria to determine the maturity of intelligence. Dr. Liu Wei told the Qianjia.com reporter. Responsive Microelectronics is a VLSI chip design company. Since its founding more than a decade ago, the company has been focusing on the design of integrated circuit chips, the research and development of IoT core communication technologies, and especially the development of core technologies such as power line carrier communication. Networking, smart homes, smart cities, smart buildings, energy management and other intelligent object-linked systems provide communication links, information awareness and other specialized chips and application solutions.
According to Dr. Liu Wei, this photo exhibition, Lihe Microelectronics brought Powerline Communication Technology (PowerIoT), which is connected to various intelligent terminal devices through power line carrier and power line carrier +433 wireless dual-mode communication technology to realize intelligence. Control. Under the wave of intelligence, various smart products emerged, but the connection itself has always been the most concerned issue. Although there are many wireless communication methods on the market, due to physical barriers such as walls, floor barriers, metal shielding, etc., its limitations It is also very obvious. Based on the chip, PowerIoT smart home, intelligent building and intelligent control hardware solutions, through the original power line for communication transmission, control of various electrical equipment, a good solution to the connection problem , To make transmission more convenient and effective. Dr. Liu Wei also said that the smart home solution in this exhibition combines voice control and power line carrier + wireless dual-mode communication technology. The most core application of dual-mode technology in the program is in the gateway, It is mainly used for voice receiving, converting the communication protocol of the terminal equipment, and realizing human-machine interactive connection of smart home control. Households use more convenient, it is a command word, easy control of terminal equipment.
As we all know, the backdrop of China's core development is the grand blueprint and passion of each segment. At the same time, it is affected by AI, Internet of Things, cloud computing, storage and cloud services. The application and performance of the application in China presented a unique personality and attractiveness. According to Dr. Liu Xin, based on the power line carrier and PLC+RF wireless dual-mode communication technology, Microelectronics has realized intelligent management of intelligent street lamps, including automatic event reporting. Automatic failure reporting, automatic alarms and other functions not only improve service efficiency, but also play an important role in promoting the construction of smart cities.
How can I get out of the dilemma of domestic chips?
The ZTE incident once again sounded the alarm for the Chinese chip industry. For China's IC industry, chip manufacturing capabilities will not form competitive advantages in capital, talents and ecology in a short period of time, and how to get out of the long-term difficulties. It requires the attention and reflection of the chip companies and even the national macro-policy level. Dr. Liu Wei said that how to break through the domestic chip industry, a substantive issue is the research and development of core technologies. Domestic chip companies, high-tech enterprises, and even scientific research. Institutions, institutions, should focus on core technologies, enhance their independent research and development capabilities, in order to grasp the right to speak in the chip market.
Dr. Liu Wei said that the current smart home market potential has not yet been fully developed, including intelligent buildings, energy management, smart cities and other fields are still in the early stages, the core reason is that the core technology is not resolved, the relevant standards have not been formed. As a technology upstream enterprise of the smart home industry chain, Microelectronics will continue to expand new application areas in providing dedicated chips and application solutions. According to Dr. Liu Wei, Lihe Microelectronics focuses on chip design and core communication technology research and development. The national standard GB31983-31 for low-voltage power line carrier communication technology was officially promulgated in May 2017, providing standardized technical support for the application of power line communication technology in related fields.
Is the chip investment really 'bloodless?'
In the primary market, the chip industry has long been in a tepid state because of high input costs, high thresholds, long periods, etc. There are also investors who shouted that they are not investing in chips, but that they are not investing in blood. Dr. Liu Wei said that chip technology is a special field. On the one hand, it has gathered a large number of high-end talents. The technical threshold is high and the research and development cycle is long. If it is from an investment perspective, the return is too slow and the risk is too great. On the one hand, it is vital to the country and to the development of various industries. Therefore, it should be treated specially at the national level or at other investment levels. Long-term observation. It is normal for a certain technology or field of the chip to be ineffective for five years, but It is also crucial. Once it breaks through, it may be a big leap for the country and the enterprise. For the chip industry, it cannot be treated with quick success and quick attitude.
Dr. Liu Wei also introduced the future market layout of Lihe Microelectronics to Qianjia.com. In terms of smart grid applications, State Grid and China Southern Power Grid are still in great demand; non-smart grid applications include smart cities, smart street lights, and smart homes. , smart hotels, intelligent buildings, energy management, solar power, battery monitoring, smart home appliances, etc., will accelerate the pace to help the application of smart cities.
Without the support of core technologies, it is difficult for any industry to develop healthily and continuously. For the chip industry, the chip technology, communication technology, protocol technology, and application technology behind it are all key. Only by solving these core problems can the industry develop benignly. Otherwise, it will only stay on the surface. Dr. Liu Wei said that Lihe Microelectronics will continue to adhere to independent research and development, providing core upstream communication technology for intelligent terminal equipment manufacturers, helping China's chip industry and the development of the Internet of Things industry.
